Abstract

When charging is performed at home of a user of a vehicle, a processor performs first charging control to start the charging after an elapse of a standby time based on a time required for elimination of polarization of a battery pack and, when the charging is performed at a place other than the home, the processor performs second charging control to start the charging before the elapse of the standby time. The processor performs control to estimate the SOH, after each of the first charging control and the second charging control.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A charging control device that performs control for charging of a secondary battery mounted on a vehicle, the charging control device comprising:
 a first processor that performs control to estimate a state of health SOH of the secondary battery, using an amount of change in a state of charge SOC of the secondary battery at a time when the charging has been performed and using an amount of charging power at the time when the charging has been performed; and   a second processor that controls the charging, wherein   when the charging is performed at home of a user of the vehicle, the second processor performs first charging control to start the charging after an elapse of a predetermined pre-charging standby time based on a time required for elimination of polarization of the secondary battery, and   when the charging is performed at a place other than the home, the second processor performs second charging control to start the charging before the elapse of the pre-charging standby time, and   the first processor performs control to estimate the SOH after the charging by the first charging control or the second charging control is completed.   
     
     
         2 . The charging control device according to  claim 1 , wherein the first processor performs control to estimate the SOH, after an elapse of a predetermined post-charging standby time based on a time required for elimination of polarization of the secondary battery from when the charging by the first charging control is completed. 
     
     
         3 . The charging control device according to  claim 1 , wherein when the charging is performed at a place other than the home and the user gives a command to perform the first charging control, the second processor performs the first charging control instead of the second charging control. 
     
     
         4 . The charging control device according to  claim 1 , wherein when the charging is performed at a place other than the home and the charging is scheduled to be performed longer than the pre-charging standby time by a predetermined time or more, the second processor performs the first charging control instead of the second charging control. 
     
     
         5 . The charging control device according to  claim 1 , further comprising a position information acquisition unit that acquires information about a position of the vehicle, wherein
 based on the information about the position of the vehicle acquired by the position information acquisition unit, the second processor determines whether to perform the first charging control or the second charging control.
